Good catch, I hadn't noticed that in his previous post. I suspect that it very well *does* have to do with XP. Quite some time ago I purchased an Acer Revo 1600 nettop PC (Intel ATOM CPU w/NVIDIA ION GPU). A great bang-for-the-buck system (about $200 w/Windows XP, 1GB of RAM, 250GB hard drive, HDMI out, gigabit ethernet, keyboard, and mouse). Performance was a problem under XBMC for XP. I could get around that by launching an external player (MPC-HC). You may want to download/try MPC-HC just to see if the CPU hogging goes away. Then, you'll have to decide if you want to go through the trouble of configuring things to launch MPC-HC as an external player, or change your OS. Windows 7 would work, but costs money. I suspect that you could get a Linux install working on the Mini as well, but I don't know the details. I'm using the OpenELEC.TV build for my Revo, and while they have an Intel i386 build, it seems to be designed for the newer Intel CPUs with on-board graphics, so you may not be able to make use of your AMD GPU, but it might still work (with you utilizing the on-board Intel graphics instead). The OpenELEC build works great on my Revo.
